CONNECTING BAND SAWTO POWER SOURCE

POWER CONNECTIONSA separate electrical circuit should be used for yourtools. This circuit should not be less than #12 wire andshould be protected with a 15 Amp fuse. Have a certi-fied electrician replace or repair a worn cord immediate-ly. Before connecting the motor to a power line, makesure the switch is in the “OFF” position and be sure thatthe electric current is of the same characteristics asstamped on the motor nameplate. Running on low volt-age will damage the motor.

WARNING: DO NOT EXPOSE THE TOOL TO RAINOR OPERATE THE TOOL IN DAMP LOCATIONS.

MOTOR SPECIFICATIONSYour band saw is wired for 110-120 volt, 60 Hz alternat-ing current. Before connecting the band saw to thepower source, make sure the switch is in the “OFF”position.

Use proper extension cords. Make sure your extensioncord is in good condition and is a 3-wire extension cordwhich has a 3-prong grounding type plug and a 3-polereceptacle which will accept the tool’s plug. When usingan extension cord, be sure to use one heavy enough tocarry the current of the band saw. An undersized cordwill cause a drop in line voltage resulting in loss of powerand overheating. Fig. 17 shows the correct gage to usedepending on cord length. If in doubt, use the nextheavier gage. The smaller the gage number, the heavierthe cord.

ACCESSORY RIP FENCE OPERATION AND ADJUSTMENTS

DUST CHUTEA built-in dust chute (A) Fig. 43, on your bench band sawis equipped with a 1-1/2" I.D. opening that can easily beconnected to a dust collection system.

IDENTIFICATION PLATEThe identification plate (B) Fig. 43, is located at the rearof the machine near the motor. The Model No. and SerialNo. are located on this plate. Please write these numberson the front cover of this manual for future reference.

The accessory rip fence (A ) Fig. 42, can be moved alongthe table surface by lifting lock lever (B) and sliding therip fence (A) to the desired location on the table. Pushdown on lever (B) to firmly lock rip fence in position onthe table. When the rip fence (A) is locked to the bandsaw table, it should be parallel to the miter gage slot (D).If an adjustment is necessary, proceed as follows:

1. DISCONNECT MACHINE FROM THE POWERSOURCE.

2. Loosen two screws (E) Fig. 42, and raise lockinglever (B).

3. While holding rip fence bracket (F) Fig. 42 firmly,move the far end of the fence (A) until it is parallel withthe miter gage slot (D).

4. Tighten two screws (E) Fig. 42, and push down onlocking lever (B).

5. Clamping action on the rip fence (A) Fig. 42, canbe tightened or loosened by lifting locking lever (B) androtating lever (B) clockwise or counterclockwise asnecessary.

OPERATING THE BAND SAWBefore starting the machine, see that all adjustments are properly made and the guards are inplace. Turn the upper wheel by hand to make sure that everything is correct BEFORE turning onthe power.

Keep the top guide down close to the work at all times. Do not force the material against theblade too hard. Light contact with the blade will permit easier following of the line and preventundue friction, heating and work-hardening of the blade at its back edge.

KEEP THE SAW BLADE SHARP and you will find that very little forward pressure is requiredfor average cutting. Move the stock against the blade steadily and no faster than will give an easycutting movement.

Avoid twisting the blade by trying to turn sharp corners. Remember, you must saw around cor-ners.

CUTTING CURVESWhen cutting curves, turn the stock carefully so that the blade follows without twisting. If a curve is so abrupt thatit is necessary to repeatedly back up and cut a new kerf, a narrower blade, a blade with more set, or additionalrelief cuts Fig. 44, may be necessary to allow the blade to cut more efficiently. The more set a blade has, the eas-ier it will allow the stock to be turned, but the cut is usually rougher than where a medium amount of set is used.

In withdrawing the piece being cut, in order to change the cut, or for any other reason, the operator must be care-ful that he does not accidentally draw the blade off the wheels. In most cases, it is easier and safer to turn thestock and saw out through the waste material, rather than try to withdraw the stock from the blade.

BAND SAW BLADESA band saw blade is a delicate piece of steel that is subjected to tremendous strain. You canobtain long use from a band saw blade if you give it fair treatment. Be sure you use blades of theproper thickness, width and temper for the various types of material to be cut.

Always use the widest blade possible. Use the narrow blades only for sawing small, abruptcurves and for fine, delicate work. This will save blades and will produce better work. Band sawblades may be purchased, welded, set and sharpened ready for use. For cutting wood and simi-lar materials, Delta can supply blades in widths of 1/8, 1/4, and 3/8 inches.

Any one of a number of conditions may cause a band saw blade to break. Blade breakage is, insome cases, unavoidable, being the natural result of the peculiar stresses to which such bladesare subjected. It is, however, often due to avoidable causes, most often to lack of care or judg-ment on the part of the operator in mounting or adjusting the blade or guides. The most commoncauses of blade breakage are:

(1) faulty alignments and adjustments of the guides;

(2) forcing or twisting a wide blade around a curve of short radius;

(3) feeding too fast;

(4) dullness of the teeth or absence of sufficient set;

(5) excessive tensioning of the blade;

(6) top guide set too high above the work being cut;

(7) using a blade with a lumpy or improperly finished braze or weld; and

(8) continuous running of the saw blade when not in use for cutting.

Blades for the new 28-150 9" Band Saw are 59-1/2 inches long.

Always use a sharp blade. Keep it free from gum and pitch. Clean frequently with a stiff fiberbrush.

Narrow blades are used for cutting small circles or curves while the wider blades are best suitedfor straight cutting such as ripping.

Due to the low cost of blades, it is advisable to purchase new blades rather than attempt to havethem sharpened.

Make sure the blade guides are always adjusted properly as previously outlined.

Do not force or twist the blade around a curve or a very short radius.

Feed the work uniformly, allowing the blade to cut – do not feed too fast.

Do not apply excessive tension on blades. The tension is only necessary to drive the blade with-out slipping on the wheels. Narrow blades require less tension than wider blades.
